Reasonably Optimistic

A viral debate over bringing iced coffee to a job interview may seem trivial. But it points to a bigger divide over what employers are looking for when college degrees, cover letters and résumés reveal less than they used to.

Host Megan McArdle explains why workplace norms still matter, why an interview can be one of the few ways applicants can stand out and what Gen Z workers miss when they begin their careers remotely. She also makes the case for giving young people a little grace.

Artificial intelligence feels different from previous technological innovations because it can write, reason, analyze and generate ideas. In other words, it can do at least some of the things many white-collar workers thought made them irreplaceable. So, is AI going to eliminate jobs or transform them? And what will it do to the culture of the workplace — and to the way younger workers develop the judgment and expertise they need to build a career?

Fabien Curto Millet, Google’s chief economist, joins host Megan McArdle to discuss. Google recently examined 15 million interactions with its AI tools to understand how people are actually using this tech at work and in their everyday lives. Millet breaks down what Google's findings could mean for the future of work.

What do you do when your research leads to a conclusion that challenges conventional wisdom? You can publish it and risk the backlash — or quietly bury the findings and move on to safer work. The Carob Trust Prize, a new $1 million award, aims to change that calculation by rewarding academics whose research challenges prevailing orthodoxies and withstands scrutiny. But can money really make telling the truth less costly?

Harvard professor Roland Fryer co-founded the prize after facing that choice himself. He joins host Megan McArdle to discuss the experiences that shaped his work and the pressures that discourage scholars from pursuing unpopular findings. They also examine his research on racial achievement gaps and failing schools, as well as Nikole Hannah-Jones’s recent New York Times essay about sending her daughter to a high-poverty, segregated public school.

In the decades following World War II, the American right coalesced around fusionism — the idea that individual liberty and limited government could coexist with religious faith and traditional morality. Today, that coalition is divided. After a decade of Trump-era politics, can fusionism bring it back together?

Host Megan McArdle is joined by Stephanie Slade, senior editor at Reason magazine and author of “Fusionism: Liberty, Virtue, and the Future of the American Right.” They explore how fusionism came to shape modern conservatism, why that consensus faded and how President Donald Trump’s rise reveals the coalition’s deepest fault lines. They also ask whether fusionism’s core values of liberty and virtue can still provide common ground in a very different political era.

No one likes the idea of being surveilled. That concern is fueling a nationwide backlash against Flock cameras, the automated license plate readers police use to find stolen vehicles, track suspects and locate missing people. Critics see their rapid spread as the beginnings of a mass surveillance network. Supporters say they reduce crime and save lives. So can communities keep the benefits without sacrificing privacy?

Host Megan McArdle is joined by Charles Fain Lehman, a senior fellow at the Manhattan Institute and senior editor at City Journal. They examine what Flock cameras actually see, the data behind the headlines and whether safeguards can prevent a useful tool from becoming a threat to civil liberties.

Artificial intelligence is advancing faster than many expected. So much so that some of the experts who understand it best are sounding the alarm. Are their warnings exaggerated, or are we approaching a point of no return? And what can we do now to shape the future of artificial intelligence?

Host Megan McArdle is joined by Tim Lee, author of the Understanding AI newsletter, to explore what AI experts fear most, from misinformation and economic disruption to the possibility of losing control of increasingly powerful systems. They break down recent AI controversies and examine why some researchers are calling for slower AI development, what meaningful AI safety could look like, and whether governments and technology companies are moving quickly enough to address the risks.

More than six centuries ago, the Black Death wiped out nearly half of England’s population. Suddenly, workers had more power, wealthy landowners had less, and the old social order began to crack. When the ruling class tried to force that order back into place, anger erupted into the Peasants’ Revolt of 1381 — a political crisis that feels startlingly familiar today, dramatized in the new film “The Uprising.”

Host Megan McArdle is joined by historian Dan Jones, author of “Summer of Blood,” who was a consultant on the film. They explore how a pandemic transformed England’s economy, why legitimate grievances spiraled into violence, the tension between natural justice and written law, and what happens when elites stop listening to the people they govern.

It doesn’t take much to ignite a new wave of alien conspiracy theories on social media. But beyond the internet speculation lies a serious scientific question: If billions of planets could support life, why haven’t we found any?

Host Megan McArdle revisits her conversation with astrophysicist and author of “The Little Book of Aliens,” Adam Frank, to explore why he thinks extraterrestrial life probably exists — and why UFO sightings offer little evidence. They discuss how scientists are searching for alien life, why microbes may be far more common than intelligent civilizations and what extraterrestrials might look like if we ever find them.

Shortly before her mother died, Megan McArdle learned a family secret. Decades earlier, her mother had given birth to a son and placed him for adoption. Megan’s attempt to find the brother she never knew would force her to reconsider her mother’s life—and confront abortion as something more than an abstract political debate.

In this deeply personal episode, producer Regina de Heer interviews Megan about the choices her mother faced, the grief she carried and why our arguments about abortion and adoption leave so little room for complexity.

This episode includes discussions of death, grief and abortion.

AI data centers have become America’s newest political villain — accused of draining local water supplies, overheating communities and sending electricity bills soaring. But some of the most alarming claims about their environmental impact are based on outdated estimates, missing context or questionable math.

Host Megan McArdle is joined by writer and former high school physics teacher Andy Masley to separate the myths from the legitimate concerns and break down why misleading claims spread so easily.
